飞书机器人交互demo golang版
飞书现在被广泛应用，本司也不例外，飞书机器人功能可扩展性还是不错的，这几天研究了一下，发现官方demo只有python版本的，不太方便go的用户拓展，所以抽时间将官方的python版改写为go版本，将每个函数都用go重新写了一下，并将代码放上来，供大家参考。
//主函数的部分如下：
package main
import (
"encoding/json"
"fmt"
"io/ioutil"
"log"
"net/http"
)
var err error
var Port = ":8086"
var APP_ID = "cli_xxxxxxxxxxx"
var APP_SECRET = "J6pwxxxxxxxxxxxxxxgEwc"
var APP_VERIFICATION_TOKEN = "9Y7nTn5d1CxxxxxxxxxxxxxxaeYOC"
func myHandler(w http.ResponseWriter, r *http.Request) {
var bodyContent ReqBody
bodyData, err := ioutil.ReadAll(r.Body)
if err != nil {
return
}else{
err = json.Unmarshal(bodyData, &bodyContent)
if bodyContent.Token != APP_VERIFICATION_TOKEN{
fmt.Printf("verification token not match, token =%v", bodyContent.Token)
return
}
if bodyContent.Type == "url_verification"{
rsp:=handle_request_url_verify(bodyData)
w.Header().Set("Content-Type", "application/json")
w.WriteHeader(200)
_, _ = w.Write(rsp)
}else if bodyContent.Type == "event_callback"{
if bodyContent.Event.Type=="message"{
handle_message(bodyContent)
}
}
//fmt.Printf(string(bodyData))
}
}
func main(){
http.HandleFunc("/", myHandler) // 设置访问路由
fmt.Printf("start at port%v\n",Port)
log.Fatal(http.ListenAndServe(Port, nil))
}其他函数的部分如下：

return
}这个默认是不支持加密通信的，需要使用加密通信的小伙伴自己写aes的部分吧。
